Scott Parker has suggested that Chelsea will be dreading the prospect of hosting in-form West Ham United at Stamford Bridge on Saturday.
They have managed a slew of high-profile victories along the way, with Arsenal, Manchester City and Liverpool all falling victim to the Irons.
Under Jose Mourinho, Chelsea also lost to Bilic and co back in October, and ex-West Ham midfielder Parker - who also played for the Blues - says that the East Londoners can complete the double this weekend.
"I honestly don't think there is a team in the Premier League who would relish playing against Slaven's West Ham nowadays," he told the Irons' official website.
"Even teams like Manchester United, Arsenal and my old club Chelsea, who West Ham travel to face on Saturday, will not fancy it, and the key for the Hammers now is to keep this momentum up and maintain their level of performance over a few seasons."
Victory for West Ham would take them into the top four with eight games to go, though Man City can usurp them again by beating Manchester United on Sunday.
